1. In a dividednut, the combination with a pair of jaws having their bases slotted, of

bases of which are. provided with eccentric slots, of springs within thejaws for forcin the same apart, pins projecting into an adapted to travel in said slots, and means pins to travel in the slots to 3. In a' device of the character described, the'combination with a pair of jaws having atheir bases slotted, of springs within the jaws for-forcing the same apart, a rotary pair of pins travelin in the slots designed to close I the jaws, and springs within the jaws for having a lug,

rojecting andle for a the combination with a'hanger frame, of a jaws carried thereby, a latch carried by 'the hanger frame, a pawl engaging the latch and means adapted to contact with said pawl to thereby release the latch and open said jaws.

5. In a device of the character described,

the combination with a hanger frame, of a pair of jaws carried vthereby, adapted'to be engaged by the jaws, a crank handle for closing said jaws, said-handle a latch having a portion pro jecting into engagement with said lug, a pawl engaging s'ai latch. and a cam secured to said support and designed .to operate said pawl to, release the catch from the lug and permit the jaws to'be' disengaged from the support; f I
